To all whom it may concern:

Be it lmown that I, HENRY DOLIER, Jr., a citizen of the Un'ited'States,residing at Bridgeport, county of 'Fairfield, State of Connecticut, haveinvented an Improvement in Reflector Holders, of which the following isa specification. I

This invention has'for its object to :provide a reflector holder adaptedfor general use and especially adapted for use in connection withporcelain lampsockets. A further object of the invention is to provide areflector holder which may be either permanently or detachably securedto the'lamp socket, which will hold the heaviest reflectors rig idly andsecurely, and which will permit the reflector to be removed withoutinterference with the lamp socket. k

With these and other objects in view, I have devised the novel reflectorholder which I will now describe,'referring' to the accompanying drawingforming a part of this specification and using reference characters toindicate the several parts 2- Figure 1 is an elevation showing my novelreflector holder in use;

Fig. 2 a section on the line 2'-2 in'Fig.

with the reflector removed; I

Fig. 3 an elevation corresponding with Fig. 1, showing theloc'king'members in the releasing position, and the reflector detachedFig. 4: an elevation on a reduced scale showing another mode ofattaching the holder to a lamp socket, and I Fig. 5 is a detail 'viewion an enlarged scale corresponding therewithl In Figs. 1, 2 and 3, 10den'otesaone-part porcelain lamp socket, and 11 a shade or reflector.The neck of the reflector, or an extension by which it is carried,isprovided with a groove 12 which is engaged by the holder. The specialconstruction of the socket is unimportant so far asthe present inventionis concerned. It is suiiicientto say that the porcelain body ofthesocket is secured to a metallic cap 13 which in turn'is secured to atube14: through which the electrical connections pass.

'My novel holder comprises'essentially a plurality of resilient lockingmembers, in the present instance three, each formed from a'single pieceof wire. The mid-length of the piece of wire 'is bent to form anarcshaped gripper 15*which is adapted to pass into the groovein' theneck of a reflector or extension and the curvature ofwhichcorrespondswith the curvature of the neck at the baseof the groove. At'the endsf'ofthe gripper, the wire is bent outward, 2133.11 16, so as to cleartheupp'er end 01": the neck, and is then bent upward and inward to formarms 17, the upper ends of the arms being bent inward at substantiallyright angles'and passed into holes 18 in the cap. A band 19 near theupper end of the porcelain body incloses the body and the arms tightlyand retains the holder securely in place. The locking membersareof'course formed by automatic machinery and the wire is given a setwhich causes the looking members,.whenassembled, to normally springoutward "radially, the gripper's normally separating and springing outward far enough to disengage them entirely from the-groove'in the neck,so' that in the normal or releasing position of the locking members, asin'Fig. 3, the neck of a reflector or extensionmay be freely'passe'dinward between the grippers 'or may be removed from between thegrippers. As a means of securely retaining the locking members in thelocking position,'I provide rings 20, each of which inclosesthecontiguous arms of two locking members. Theserings-when forced downwardon'the arms, as in Fig. 1, act to draw the lower ends of thelockingmembers inward radiallyand cause the grippers to pass into the groove'in the neck and engage the base'oftlie groove firmly, thus locking fe'rsonly in the means of attaching the holder to the lamp socket. The lowerpart with a groove 21 which receives the'parts of a clamp 22. The partsare formed to an '5 are shape to fit the groove closely and are providedat their ends with ears 23 threaded to receive set screws 24 by whichthe parts are drawn together and closed tightly into the groove to lockthe holder to the socket. The locking members are made resilient andcontiguous arms of two members are inclosed in rings, as before, whichcause the locking members to grip or release a reflector. It will ofcourse be obvious that four or even more locking members may be used, ifpreferred. I find, however, that three locking members work admirably inuse.

Having thus described my invention, I claim:

1. A reflector holder adapted for attachment to a lamp socket andcomprising a plurality ofindependent resilient locking members eachformed from a single piece of wire, the mid-length of which is bent toform an arc-shaped gripper, the wire at the ends of the gripper beingbent outward to clear a reflector member as set forth, and then up wardto form arms, means for attaching the independent ends of the arms infixed posltion to a lamp socket and rings inclosing the contiguous armsof two locking members, upward or downward movement of the rings causingthe grippers to assume the releasing or looking position.

2. The combination with a lamp socket and a reflector or extensionhaving a grooved neck, of a holder comprising a plurality of independentresilient locking members, each consisting of an arc-shaped gripper andarms, means for securing the independent ends of the arms in fixedposition to the lamp socket and rings engaging the contiguous arms oftwo locking members, said rings acting when pressed downward to causethe grippers to pass into the groove and lock the reflector in place.

8. The combination with a lamp socket member and a reflector memberhaving a groove, of a holder for supporting the reflector member withrespect to said lamp socket member comprising a plurality of separateand independent locking members each having an arcuate portion adaptedto engage in said groove and arms extending longitudinally above andbelow said socket member, means for securing the upper ends of said armsin fixed relation with respect to said socket member, and membersengaging neighboring arms of neighboring locking members and movablelongitudinally for drawing said arcuate portions into said groove.

4. The combination with a lamp socket member and a reflector member, ofa holder for supporting said reflector member with respect to said lampsocket member comprising a plurality of separate and inde pendentlocking members each consisting of an integral piece having an arcuateengaging portion, upwardly extending arms at the ends of the arcuateportion, a cap secured to said socket member and having aperturesreceiving the inturned ends of said arms, and members engagingneighboring arms of neighboring locking members and movablelongitudinally thereof for causing said arcuite portions to engage saidreflector mem- 5. The combination with a lamp socket member and areflector member, of a holder for supporting said reflector member withrespect to said lamp socket member comprising a plurality of separateand independent locking members each consisting of an integral piecehaving an arcuate engaging portion, outwardly extending portions at theends of said arcuate portion, upwardly extending arms at the ends ofsaid outwardly extending portions, means securing the upper ends of saidarms to said lamp socket member, and members engaging neighboring armsof neighboring locking members and movable longitudinally thereof forcausing said arcuate portions to engage said reflector member.

6. The combination with a lamp socket member and a reflector member, ofa holder for supporting said reflector member with respect to said lampsocket member comprisinga plurality of separate and independentresilient locking members, each comprising an arcuate portion,longitudinally extending arms at opposite ends of said arcuate portion,a cap secured to said lamp socket memher, the free ends of said armssecured by,

said cap, and members engaging and movable longitudinally of arms ofneighboring locking members to bring said arcuate portions intoengagement with said reflector member.

7. The combination with a lamp socket member and a reflector member, ofa holder for supporting said reflector member with respect to said lampsocket member comprising a plurality of separate and independentresilient locking members, each comprising an arcuate portion,longitudinally extending arms at opposite ends of said arcuate portion,a cap secured to said lamp socket member, the free ends of said armssecured by said cap, members engaging and movable longitudinally of armsof neighboring locking members to bring said arcuate portions intoengagement with said reflector member, and a circumferential bandengaging said arms.

8. The combination with a porcelain lamp socket member, of a metalliccap to which said member is secured, a reflector member,

a holder for supporting said reflector member with respect to said lampsocket member comprising a plurality of separate and independentresilient members each comprising an arcuate portion, upwardly extendingarms extending inwardly above said lamp socket member and held by saidcap and members engaging and movable longitudinally of said arms ofneighboring resilient members for causing said arcuate portions 10 toengage said reflector member.

In testimony whereof I affix my signature.
